Author loses five recent papers for copying multiple figures, unspecified “overlap”

Two journals have retracted five recent papers by a researcher in Saudi Arabia after discovering extensive overlap, which one journal called plagiarism.

In one retracted paper, all schemes and figures are copies from other publications; in another, more than half of the figures are lifted. The journal that retracted the other three papers did not provide details about the nature of the overlap.

All five retracted papers—originally published within the last 15 months—have the same corresponding author: Soliman Mahmoud Soliman Abdalla, a professor of physics at King Abdulaziz University in Jeddah, Saudi Arabia.

According to a spokesperson for Polymers, readers flagged two papers in July 2017; both were retracted in August.

The spokesperson for Polymers told us that the journal ran the papers through the plagiarism detection software, iThenticate, but found “no significant levels of copied text.” The journal says it missed the overlap because:

Five retractions for engineering duo in South Korea over duplication, fraudulent data

An engineering student in South Korea and a professor have retracted five papers from four different journals for reasons ranging from figure duplication to manipulated or fraudulent data.

Jae Hyo Park, who is pursuing his PhD, and Seung Ki Joo, a professor in the department of material science and engineering at Seoul National University in South Korea, appear on all five papers as first and last author, respectively.

According to an official at IOP Publishing, the retractions began when a third party contacted them last March about “potential misconduct” in a paper published earlier that year in one of its journals—Journal of Physics D: Applied Physics. The IOP official Simon Davies explained: Continue reading Five retractions for engineering duo in South Korea over duplication, fraudulent data

Research misconduct finding — which university won’t discuss — leads to second retraction for prominent physicist

A rising star in nanotechnology, Dmitri Lapotko, has received his second retraction within a month over “a finding of research misconduct” that the university will apparently only disclose on a need-to-know basis.

According to the notice, the journal’s editor and publisher issued the retraction after Lapotko’s former institution—Rice University in Houston—notified them of research misconduct and cited figure duplication issues, which meant the results “should not be relied upon and may be scientifically unsound.”

We recently covered the Belarusian physicist’s first retraction in the journal Theranostics, in which an official at Rice would not confirm a misconduct inquiry, telling us that, “Rice University’s investigations of research misconduct are confidential.”

This time, however, the retraction notice explicitly states that a Rice University research integrity officer reported research misconduct to the journal Applied Physics Letters (APL). We contacted the official, B.J. Almond, who still stuck to the original script: Continue reading Research misconduct finding — which university won’t discuss — leads to second retraction for prominent physicist

Physics paper’s results off by factor of 100

Researchers from China have retracted a physics paper after realizing an error led them to report results that were nearly 100 times too large.

What’s more, the authors omitted key findings that would enable others to reproduce their experiments.

According to the notice, the authors used a value to calculate a feature of electrons—called mobility—that “was approximately 100 times too small,” which led to results that were “100 times too large.” The notice also details several gaps in the presentation of experimental results, which preclude others from duplicating the experiments.

Here’s the retraction notice for “Bulk- and layer-heterojunction phototransistors based on poly[2-methoxy-5-(2′-ethylhexyloxy-p-phenylenevinylene)] and PbS quantum dot hybrids:” Continue reading Physics paper’s results off by factor of 100

Duplication earns retraction for nanomaterials paper that had already been corrected

Applied_Physics_Letters_cover_imageAfter earning an erratum shortly after publication in 2009, a paper in Applied Physics Letters has now been retracted for the “regrettable mistake” of duplicating an earlier paper by the researchers.

Here’s the notice for “Broadband and omnidirectional antireflection from conductive indium-tin-oxide nanocolumns prepared by glancing-angle deposition with nitrogen:” Continue reading Duplication earns retraction for nanomaterials paper that had already been corrected

Obfuscation watch: Self-plagiarism (we think) leads to retraction of nanorod paper in Applied Physics Letters

C. P. Snow famously bemoaned the gulf between science and the humanities. The following retraction might be the sort of thing that would have given the physicist-cum-author fits for its estrangement from the English language.

Writing in the latest issue of Applied Physics Letters, a team from China Singapore and MIT appear to be confessing a case of self-plagiarism in their 2005 paper, “Growth of single crystal ZnO nanorods on GaN using an aqueous solution method: (we added a link to the earlier paper)” Continue reading Obfuscation watch: Self-plagiarism (we think) leads to retraction of nanorod paper in Applied Physics Letters
